Given the reaction, 4Al + 3O22Al2O3, what is the total number of moles of aluminum oxide (Al2O3) that can be formed when 54 grams of aluminum react completely with oxygen

The correct answer is a

Nonmetals usually react by gaining electrons

☆ionisation energy increases across a period from na -> ar☆ionisation energy decreases down a group from li -> fr☆ionic radius decreases across a period from na -> cl☆ionic radius increases down a groupfrom f -> ii hope it clarifies your doubts
